5-Hydroxy-Tryptophan 100 mg by Priority One is a good source of 5-HTP‚ which is a natural chemical that may act to promote a sense of relaxation.

Specifically‚ your body can work to convert 5-HTP into a hormone called melatonin. Since melatonin plays a key role in regulating sleep patterns‚ 5-Hydroxy-Tryptophan 100 mg could potentially help you get a good night’s rest.

In addition‚ 5-HTP may aid in the production of serotonin‚ which is a neurotransmitter that might have a gentle calming effect. As a result‚ 5-Hydroxy-Tryptophan 100 mg may help address certain symptoms related to a low mood.

Moreover‚ 5-HTP could potentially work to alleviate discomfort associated with minor headaches.

For these reasons‚ every capsule of this Priority One supplement provides 100 milligrams of 5-HTP derived from the seeds of a West African plant known as giffonia simpicifolia.

Each bottle of Priority One’s 5-Hydroxy-Tryptophan 100 mg contains 90 vegetarian capsules.

      Seasonal Affective Disorder

      from Winona, MN on 1/26/2013
      My daughter just moved to Alaska in December. She is prone to ups and downs and 5-HTP is helping her to combat the long dark winter days and nights.


      Natural aid rather than chemical or sythetic drug.


      A bit expensive but if it works well it will be worth every penny.
